I've searched through most of the other complaints trying to find a way to fix my problem but nothings worked.

I was playing and quest helper was working fine, and then the next moment its not

Please give me as many suggestions as possible to fix it, i've grown rather fond of quest helper

Try /qh hardreset

If that doesn't work read this Sticky.

Or maybe you went into a zone that doesn't work with QuestHelper, such as Dalaran, the Death Knight starting area, or any instance.

It happened to me aswell, i was getting run through some group quests in nagrand, and then when i picked up these quests it wouldnt track them [The Ultimate Bloodsport] [Buying Time] [Gurok the Usurper] I also already had [Corki's Ransom] and it never tracked it.

I don't think QH tracks group quests unless you specifically turn on that feature.
